Use WordPress to print a RSS feed for Eventbrite attendees
Today I was working on the WordCamp.LA site. I was trying to show the “attendee list” on the attendees page with out having to update the page every day.
Since I am using EventBrite to promote and sell ticket to the event I can collect info from there list. Evey one who purchases a ticket gets put into the ticketed database which you can view with either RSS or OPML.
I chose to use RSS and the WordPress core file rss.php
.
In the functions.php file I’ve added this function:
function attendee_feed_print_2009() { global $wpdb; include_once( ABSPATH . WPINC . '/rss.php' ); $rss = fetch_rss( 'http://www.eventbrite.com/rss/event_list_attendees/384870157' ); $items = array_slice( $rss->items, 0 );
Where I’ve named my function, and included the core RSS file from WordPress. I also told it to fetch the feed from the address (alternatively you can use any feed link you like).
if ( empty( $items ) ) echo '<ul style="list-style-type: none; list-style-image: none; list-style-position: outside;"><li>No items</li></ul>'; else foreach ( $items as $item ) : ?> <ul style="list-style-type:none; list-style-image:none; list-style-position:outside; margin-bottom: 0px"> <li><!--<strong><?php echo $item[ 'title' ]; //User name ?></strong><br />--> <?php echo $item[ 'content' ][ 'encoded' ]; ?> <hr style="border: 1px solid #ddd; margin-bottom: 8px" /> </li> </ul> <?php endforeach;
I then added the core style to fit this current feed.
And the final out come looks like this:
function attendee_feed_print_2009() { global $wpdb; include_once( ABSPATH . WPINC . '/rss.php' ); $rss = fetch_rss( 'http://www.eventbrite.com/rss/event_list_attendees/384870157' ); $items = array_slice( $rss->items, 0 ); if ( empty( $items ) ) echo '<ul style="list-style-type: none; list-style-image: none; list-style-position: outside;"><li>No items</li></ul>'; else foreach ( $items as $item ) : ?> <ul style="list-style-type:none; list-style-image:none; list-style-position:outside; margin-bottom: 0px"> <li><!--<strong><?php echo $item[ 'title' ]; //User name ?></strong><br />--> <?php echo $item[ 'content' ][ 'encoded' ]; ?> <hr style="border: 1px solid #ddd; margin-bottom: 8px" /> </li> </ul> <?php endforeach; }
Don’t forget to wrap the code in <?php
?>
I want to thank John Kolbert for helping me with printing the content:encoded
portion. http://pastebin.com/m1588fb30

How to: Add a contact me via Skype™ button
This little trick is really simple and easy. All you need to do is plug this line of code anywhere you would like to use the text.
<a onclick="return skypeCheck();" href="skype:austin.passy?call">Call me on Skype!</a>
That’s is, pretty simple huh? Just make sure you change skype:austin.passy to your user name!
Want a test? Well, please use the text button, as I was getting to many call’s and hangups: Call me on Skype! Message me on Skype!
Thanks to Shayne for this code!
Update:
I was reminded by Shayne that you will have to add this script into your header.php
file:
<script type="text/javascript" src="http://download.skype.com/share/skypebuttons/js/skypeCheck.js"> </script>
That way if the user doesn’t have Skype, they will be prompted to download it if they would like :).

How to: show/hide a widget in WordPress with jQuery
In a previous post I talked about how to show/hide a single div
html code with a search inside. Today I’d like to show you how I implemented jQuery into my new theme.
As seen in the current theme, I am using jQuery to animate the show/hide or as known as the css style display: none;
.
Since I am using a custom child theme on my site, and have Hybrid theme as my parent, the widgets or sidebar section is different than may be in your theme. But just apply the the style’s as follows to your theme.
First make sure that your WordPress site is calling jQuery, by plugging in this code into your header.php
file above the <?php wp_head(); ?>
text:
<?php wp_enqueue_script('jquery'); ?>
Then anywhere above the </head
>, plug this code in:
<script type="text/javascript"> function toggleWidgets() { $('#primary h3.widget-title').addClass('plus'); $('#primary h3.widget-title').click(function() { $(this).toggleClass('plus').toggleClass('minus').next().toggle(180); }); } $(document).ready(function() { toggleWidgets(); } </script>
That’s it. Pretty simple huh.
So lets go over what the code does.
$('#primary h3.widget-title').addClass('plus');
This line finds all <h3>
tags with the class widget-title
inside the ID parameter of #primary
and adds a class of plus
.
Then
$('#primary h3.widget-title').click(function() { $(this).toggleClass('plus').toggleClass('minus').next().toggle(180); });
Will apply a click function. When the H3 tag is clicked it will remove the class plus
and add the class minus
.
Then the code that says .next
will then toggle the “next” element after the <h3> title.
